EARHRING OR OTHER JEWELRY.

SPECIFCATION forming part of Letters Patent No. 39S,78"7, dated February 26, 1889.

Application filed February 24, 1888. Serial No. ZGJ 45. (No model.)

To CLZZ whom it may concern:

Beit known that I, ADOLPH LUTHY, of N ew York city, New York, have invented certain new and useful Improvements in Ear-Rings and other Jewelry, of which the following is a specication.

This invention relates more particularly to car-rings of that class known as solitaires which are fastened to the ear by means of a sha-nk or stem thrust through the hole in the lobe of the car and provided with some sort of fastening device engaging the rear side of the lobe.

The invention is also applicable to other articles of ,jewelry which are designed to be fastened in similar manner.

According' to my invention the ornamental head or setting is provided with a stem or shank projectin perpendicularlyor rearwardly from its base, and with a fastening-arm in the nature of a crank projecting lateral ly from said stein and adjustable toward and from the base. 'llhislateral crank-arm is first inserted through the hole in the lobe ot' the ear, the stem from the end of which it projects following it and remaining in the hole after the arm has passed through. The arm is then screwed or oi hcrwise adjusted toward the base until the lobe of the car is clamped between them with sufficient firmness io prevent disi placement.

i-Xccording to the inel'erred construction the r stem projects rigidi)v from the center ofthe base and the adjustable arm terminates in a sleeve or hub7 which screws on the stem, so

that when the arm is adjusted toward the base, in order to clamp the ear,ihe end of the stem p rotrud es sufficiently beyond the arm to preclude the possibility ol' the stem and arm passing through the hole in the car and tht-reby releasing the device.

ln the accompanying drawings, lfigurc l is a side elevation of myimproved ear-solitaire, showing theprefcrred construction on a largo scale. Fig. 2 a similar view showing the arm partially in section and illustrating the device as clamped to the ear, a portion of which is indicated. Fig. 3 is a rear elevation of the fastening dcvice,the ornamental porear and stands at the rear side thereof. arm l) is then turned by the handle d, the

tion of the head or settingbeingomitted. Fig. et is an axial section illustrating a modified construction.

Let A designate the usual base or back plate of the solitaire upon which the setting B is mounted, or which base may itself be ornamental and constitute the head or outer portion of the article of jewelry.

C is the stem or shank which projects per pendicularlyv from the center of the. base A and toward the rear thereof.

D is the laterally-projecting fastening arm orcranli, which is ad justable toward and from the base A in a direction parallel with the axis of the stem C.

In the construction shown in Figs. l, 2, and l the arm l) is formed with a tubular sleeve, E, which is internally screw-threaded to iit the internal threads on the stem C, on which it screws toward or from the base A. The stem C is formed with a partial head or enlargement, c, which serves to prevent the sleeve E being so far nnscrewed as to separale it from the stem.

The end of the arm l.) is turned outwardly at d, in order to form a sort of handle b v which to turn the arm l') in screwing it toward or from the base. or by which the arm maY be conveniently held in order to screw the base toward or from it in fastening or unfastening the solitaire. rlfhis handle portion, however, is not essential.

In Fig. l the arm l) is shown as screwed ont to its extreme position, where it constitutes virtually a lateral continuation of the end ot' the stem C. lt isin this position of the parts that the solitaire is applied to the car, the end d of the arm D being first inserted, the arm following it, and thc stem C finally coming into they hole in the lobe of the ear, at which time the arm l) has emerged from thel The head B being held stationary, or else the arm D is held stationary by the handle d and the head B turned7 the direction of motion in either case being such that the arm D and base A are drawn together until they gentlT clamp or clasp the ear between them, as

shown in Fig. 2. Then this is done, the rear portion of the stem C projects a considerable distance beyond the arm D, so that the end of the stem, in combination with the arm, forms a head or enlargement against the rear side of the ear, which is altogether too wide Vmake the sleeve E as thin as is consistent with strength, in order that it shall not constitute too great an enlargement of the stem. The junction of the arm D with the sleeve E should be made by a gentle curve, in order to facilitate insertion into the ear.

The stop-head c on the stem C should he made to fit closely against the outer end of the sleeve when the latter is screwed out, and should be rounded upon its exterior in such manner as to form a continuation of the rounded exterior of the sieeve and arm and afford no abrupt edge or angle.

Fig. L shows a modified construction wherein the stem C is Vmade to screw into the base A, and the arm D is made in one piece with the stem projecting.laterally from the end thereof. The setting B is in this construction shown as fastened directly on the front end of the screw, and consequently adjustable relatively to the base A, which latter becomes in effect a nut turning on the screw. The operation is similar to that of the construction iirst described, the arm D being first inserted through the hole and resting against the rear s ide of the ear, after which the base A is screwed toward it on the screw C until the lobe of the ear is confined with suitable iirmness between it and the arm D.

My invention is designed especially to supersede fastenings for ear-solitaires of that l class wherein a nut or disk screws on a threaded shank passed through the hole in the ear in order to clamp the lobe of theY ear between it and the base plate or head. Such fastenings are subject to the disadvantage that the nut is a separate part which must be detached before the ear-ring can be fastened to the ear, and is consequently liable to be lost, in addition to which difculty is eXpel rienced in screwing on the nut in the position it necessarily occupies, where it is out of sight and inconvenient to reach. These disadvantages are entirely obviated by my invention, the parts of which are so constructed that they cannot be separated, and with which it is not necessary to start the screw-threads intocoincidence in screwing the two parts together.

My invention is also applicable to other analogous articles of jewelry--such, for example, as studs for the eyelet-holes of shirtfronts.

I claim in ear-rings or other analogous articles of jewelry the following defined novel features, substantially as hereinbefore specified, viz:

l. The combination, with the base, of a stem projecting therefrom and a laterallyprojecting fastening crank-arm borne by said stem, and constructed to be adjustable toward and from the base.

2. The combination, with the base, of a stem projecting therefrom and a laterallyprojecting fastening erank-armborne by said stem, and constructed with a screw-thread, whereby it is adjustable toward and from the base.

3. The combination, with the base, of a screw-threaded stem projecting rigidly therefrom and a laterally-'projecting fastening crank-arm screwing on said stem, and thereby adjustable foward and from the base.

Li. The combination, with the base, of a screw-threaded stem projecting rigidly therefrom and a laterally-projecting fastening-arm constructed with an internally-threaded arm is adjustable toward and from the base.

screw-threaded stem proj ecting rigidly therefrom and terminating in a head or enlargement and a laterally-proj ecting fastening-arm screwing on said stem, whereby it is adjustable toward and from the base and its separation from the stem is prevented.

6. The combination, with the base, of a stem projecting therefrom and a laterallyprojecting fastening-arm borne by said stem and constructed to be adjustable toward and from the base, and the outer portion of said arm'turned rearwardly to form a handle by which to turn or hold the arm.
